Code Examples

Example 1: Basic Usage with Fixed Output Voltage

In this example, we will use the XL7015 to convert a 12V input voltage to a fixed 5V output voltage.

```c
// Connect VIN to 12V power source
// Connect VOUT to load (e.g., microcontroller or sensor)
// Connect GND to ground
// Connect EN to digital output (e.g., GPIO pin)

void setup() {
  pinMode(EN, OUTPUT);
  digitalWrite(EN, HIGH); // Enable the converter
}

void loop() {
  // The XL7015 will output a fixed 5V voltage
}
```

Example 2: Adjustable Output Voltage with Potentiometer

In this example, we will use the XL7015 to convert a 9V input voltage to an adjustable output voltage using a potentiometer.

```c
// Connect VIN to 9V power source
// Connect VOUT to load (e.g., microcontroller or sensor)
// Connect GND to ground
// Connect EN to digital output (e.g., GPIO pin)
// Connect ADJ to potentiometer wiper terminal
// Connect potentiometer terminals to VOUT and GND

void setup() {
  pinMode(EN, OUTPUT);
  digitalWrite(EN, HIGH); // Enable the converter
}

void loop() {
  int potValue = analogRead(potentiometerPin); // Read potentiometer value
  float outputVoltage = (potValue / 1023.0)  32.0; // Calculate output voltage
  // The XL7015 will output the calculated voltage
}
```

Example 3: Using the XL7015 with a Microcontroller

In this example, we will use the XL7015 to power a microcontroller (e.g., Arduino) from a single-cell Li-ion battery.

```c
// Connect VIN to Li-ion battery (3.7V to 4.2V)
// Connect VOUT to microcontroller VCC pin
// Connect GND to microcontroller GND pin
// Connect EN to microcontroller digital output (e.g., GPIO pin)

void setup() {
  pinMode(EN, OUTPUT);
  digitalWrite(EN, HIGH); // Enable the converter
}

void loop() {
  // The XL7015 will output a fixed 3.3V voltage to power the microcontroller
}
```
